Application illed May 3, 1913. Serial No. 765,274.

To al Awhom fit may concern:

e it known that l, lll-:Nur A. DnnrrmN, a citizen of United States, residing at Chicago. in the county ot' (look and State of Illinois, have invented certain new and useful Improvements inGus-W'ashers, of which lho following is a specification.

'.lhih` intention relates to improvements in gas washers. and has for an object to provide an improved form of device Vin which the gus is forced to travel through :i tortuous passage, the size ot which may be varied at will.

Another object is to provide,. in conjunction with said passage, a spray for wetting the surfaces of the passage and thereby assisting in the deposit and collection of the dust and carbonaceons material carried by the gas.

Another object is to provide means for supplying spray fluid to the spraying means. and Jor supplying steam or other heated fluid to such spraying means for the purpose ot' melting the deposited material from the surfaces of the passage when it is desired to clean the same.

Still another object is to provide lire means vfor cleaning one of the sur aces.

This. and other objects will be set forth and made apparent in the following specification and accompanying drawings, in which;v

Figure 1 a vertical section of my imi proved device;

Fig. 2 is a similar section taken at right angles thereto along the line 2--2 of Fig. 1;

Fig. 3 is a plan View of the same, part of the cover being brohen away;

Fig. l is a transverse section along line bei of Fig, 2;

Fig. -5 is u transverse section along the line 5--5 of Fig. 1;

Fig. 6 is n detail vertical section showing the scraping plate construction.

Like numerals refer to like elements throughout the drawings, in which;

10 designates generally my cnsiuf member shown as preferablyrectangular in cross section. This casing member with the inlet opening 11, surrounded by the integral flange or boss '11. Casing 10 is further provided with the outlet aperture 13 surrounded hy reinforcing flange 1B. The outlet and inlet openings are located on different. levels and a flange 14 projects inwardly in the casing between the said the 'face and then the ot is provided.

outlet and inlet and is preferably formed integral with the casing. This flange is npertured, as indicated by sleeve member 16, provided with the central tapered bore 17 and the upper external flange 18, projects through the aperture 15, the llange 18 resting upon the casing flange 14, to Which it is detachably Secured by bolts 1S). The inner surface 17 of the sleeve 16 is provided with a continuous helical corrugaton extending from top to bottom thereof, as shown in Figs. 1 and 2.

A plug member Q0 tapered similarly to the bore of the sleeve 1G, is mounted concentrically thereof. A rod 21 constitutes a stem for the plug Q0, extending centrally therethrough, being secured thereto at one extremity by the nut 2,1 and at the other extremity of the plug by the key or pin 22 seating in the groove 22 of plug 20, as clearly shown in Fig. 2. The external surface of this plug Q0 is provided with the continuous helical corrugation complementary to the corrugation 'of the surface 17 of sleeve 16. By complementary, is meant that the corrugations of the plug site the depressions betweenA ad]acent portions of the corrugation in the inner surface of the sleeve, being similar to the fit between the threads of a threaded plug and socket, save that the plug 20 is normally spaced from the inner surface 17 of the sleeve 16, in order to provide a passage for the gas. The purpose of this construction is described below.

The operation of the structure, in so far described, is as the chamber through inlet- 11, is forced by means of the flange 14 and contacting flange 18, to travel between the corrugated surfaces of the plug 20 and .leeve 16. These corrugated surfaces serve to provide a tortuous passage for the gas which is drawnlout through the aperture 13. In its passage between the corrugated surfaces the gasws thrown back and forth by means of the corrugations and impin. es upon first one surer, thereby causing a deposit of the carried dust and carbonaceus material. By virtue of the taper of the plug and sleeve, and the complementary he ica corrugations, I may rotate the plug with respect. to the sleeve at the same time moving it longitudinally thereof to narrow the p assu ge between; at the same time maintaining the tortuous character thereof. I accomare oppofollowsz--Gas is drawn intoV numeral 15. `A

ioo

Vylfsh this result by ext/ending the rod 21 through the stuffing box construction 23, in the bottom of the casing 10. A voke Q4 is secured at its extremities by bolts 25 to the bottom of the casing il() und is provided, with the central aperture portion 26 internally threaded for engagement by the threaded portion 27 of rod 21. The thread. of the rod 27 is of a pitch the saine as that of the helix of the corrugntions of the plug and sleeve. Secured to the lower' cxtrcmity of the rod 21 is the operating wheel 253 which may be rotated to rotate the rod 2l and owing to the similarity in pitch between the said corru gntions and tho pitch of thc thread, rotation of the rod 21 will operato to rotn 'a the plug and movc the sumo nt thc sumo time longitudinally of the sleeve. In Short, the notion is similar to thatwliicii would exist were the plug and sleeve in tht-ontleed engagement, in so far as concerns the reioivo movement, However, owing to the tapar construction, tho distance between the ad went surfaces of the plug and sleeve will lc Unified :is desired, by rotating tho ping upwmoiiy or downwnrdly to increase os' door/onse the @raid dis tance, respectively. Owing to the helical construction of the oorrugntions on the sleeve and the plug the lutter muy bo Screwed downwardly into Contact with the sleeve if so desired Without interference of the oorrugntions 'on tho plug with those on the sleeve, as will hc apparent.

Located upwardly of the ping and siecve, is provided tho spray 30 adopted, to spray outwardly fluid such :is water, into the spiace between thc ping und sleeve; This Water will be wnveyod downwardly over corfu-- gated surfaces und will mmcrinlly assist. in the deposit and collection of the dust carriod bythe gus. 'To supply nfutcz" to the spraying nozzle 30, is provided 2:, fnf-31, extending upwardly into communication with :1. Huid supply pipe 32, flo rlioretlirougli lacing cow trolled by the valve A steam supply pipe 34 is `also in communication with the pipe 31, iow of steam therethrough being controlled by valve 35. i s tho water or other Huid Hows through the passage be tween the plu and sleeve and down the corrugated sur aces thereof, it collects in the bottom of casing wund is transported thorofrom by the Ushnped outlet tube 36, sealed by means of the fluid 37 therein against the How of gas therethrough. -Thc pipe 31 ex# tendsupwau'dly tlirmigh on aperture in the i f tos of thevcasmg 10, the lutter being provi c d-with un aperture or openi 38 thorethroughof grcnterfsize thnntlie. inmetcr of the plug and iiamg y18 of thcalceve i6, n
